The nuclear chief added the country has increased the number of uranium-enriching centrifuges to 6,000, noting that "their number is expected to grow." This is Tehran's latest defiance of United Nations demands to halt its nuclear program.
The latest announcement indicates that Iran installed another 2,200 new centrifuges on top of the 3,800 centrifuges that were already in place in Natanz.
According to Aghazadeh, Iran will install a total of 50,000 centrifuges in Natanz in the next five years, assuming it will be able to overcome technical problems that have been delaying its progress.
Iran began a test run on its nuclear power plant in Bushehr on Wednesday. According to Iranian reports, the pilot operation was carried out using virtual fuel rods and not real ones.
